My USB cable has a problem. I saw I was not the only one to experience this issue : my Odyssey keeps on disconnecting from my PC when I plug it with the USB cable provided with the device when I bought it).

Wifi seems to work fine.

Question : is there a way to transfer books from my Calibre Library to the device through the Wifi ?

Or should I send my device back ? (no good for me, I leave soon on a long trip and I need my Odyssey !)

Antonio.

I believe there is a way to start a content server. I think you would then just have to visit the server on the Odysseys web browser and download the books you want.
There is a Calibre forum you could ask.

This is not a unique issue. My three-week-old Odyssey does the same thing. It repeatedly disconnects from USB after a couple of minutes. If I leave it plugged in to charge, it also hangs my iMac at times.

Clearly the USB support is still (or again) broken, as others report the same issue recently.
